Make Sleep a Priority for Mental Health Promotion

This week we celebrate Sleep Awareness Week. The theme for this year is, “It’s time to be your best slept self.” Sleep is foundational for both physical and mental health. Yet, an estimated 50 – 70 million Americans report having trouble sleeping, and the numbers continue to increase annually, primarily due to poor sleep habits. On average, Americans report insufficient sleep at least 2 nights per week, and almost 40% of Americans report getting less than 6 hours of sleep per night (Grandner, M. A., & Malhotra, A., 2015). Sleep can be important piece of the treatment puzzle for anyone who is experiencing  challenges with mental health.

Sleep is a critical time for the body to restore, repair, and rejuvenate. Sleep restores the cells in the body, and toxins are washed away from the day. It is also the time when the brain goes into repair mode, and neuronal connections are activated. When a person doesn’t get adequate sleep, the overall blood flow to the brain is decreased, which disrupts memory, concentration, and the ability to think clearly. In addition, poor sleep has been associated with Type 2 Diabetes, Depression, Anxiety, ADD, Alzheimer’s Disease, Parkinson’s Disease, Stroke, Psychosis, weight gain, and poor lifestyle choices. (Amen , D., 2017).

Sleep is an essential element of mental health.  Research shows that there is a bi-directional relationship between sleep and mental health. For example, mental health disorders tend to make it harder to sleep well, and poor sleep can contribute to worsening mental health problems.  While both sleep and mental health are complex, there are many related factors, and research points to a close association between good quality sleep and mental health. Sleep can be an important component of care plans.

Here are some key research findings that highlight the connection between sleep and mental health (Suni, E., & Dimitriu, A., 2020):

  • 75% of people who experience depression report symptoms of insomnia. Sleeping problems have historically been attributed as a side effect of depression, but there is growing research that insomnia may induce or worsen depression.
  • 90% of veterans with combat related PTSD experience symptoms of insomnia. People with PTSD often experience re-occurring, unwanted, distressing thoughts, and often experience nightmares, along with hyperarousal which can inhibit sleep.
  • Anxiety disorders have a strong association with sleep problems. Worry, fear, and hyperarousal all contribute to insomnia. In addition, chronic insomnia may be a risk factor for developing an anxiety disorder.
  • People who experience Bipolar Disorder often see their sleep connected with the state of their mood. During manic periods, a person may sleep much less than during periods of depression. Between episodes of mania and depression, sleep disruption is often reported. Treatment of insomnia has been shown to help improve mood fluctuations for people who experience bipolar disorder.
  • People who experience schizophrenia are more likely to experience insomnia, along with circadian rhythm disorders. In addition, some medications used to treat schizophrenia worsen sleep. Treating sleep problems for people who experience schizophrenia have been shown to have improve treatment outcomes.
  • People with ADHD may have trouble falling asleep, frequently wake up, or feel extreme daytime sleepiness. People with ADHD also tend to experience higher rates of obstructive sleep apnea and restless leg syndrome.
  • Children and adolescents who are on the autism spectrum are more likely to experience sleep problems, such as insomnia and sleep-disordered breathing. Sleep problems can contribute to decreased quality of life and worsening symptoms of Autism.
  • People who experience sleep problems are at increased risk for suicidal behaviors (Suni, E., & Dimitriu, A., 2020).

Sleep is a crucial to mental health. One treatment protocol that has been effective is Cognitive Behavioral Therapy for Insomnia (CBT-I) which has been shown to help improve sleep. Patients identify sleep as being one of the most relevant aspects of their health and quality of life (Grandner, M. A., & Malhotra, A., 2015). Yet, clinicians often don’t ask about sleep. For example, one study found that only 43% of primary care provider’s ask about sleep, whereas 80% ask about exercise, and 79% ask about healthy diet. In addition, only 16% of providers believed it was important to talk about sleep with their patients. Here is a list of basic questions that may be helpful when thinking about how to ask your patient about sleep:

  1. How are you sleeping?
  2. How well rested do you feel when you wake up in the morning?
  3. When you go to bed, how long does it take for you to fall asleep?
  4. How do you feel during the day?
  5. How restful is the sleep that you get?
  6. If you wake up in the middle of the night, do you easily fall back to sleep?
  7. Do you wake up too early in the morning, and find you are unable to go back to sleep?
  8. What would your best slept self feel like?

Having trouble falling asleep, experiencing frequent sleep disruptions, and feeling fatigue throughout the day are all signs of poor sleep hygiene. After discussing sleep with client’s, it can be helpful to share basic sleep hygiene tips with them. The National Sleep Foundation just published their annual poll to understand how many Americans are engaging in health behaviors that are associated with good sleep. Here’s what they found (National Sleep Foundation, 2022):

  • Almost ½ of Americans report not being exposed to bright light in doors in the morning (49%), or in the afternoon (47%).
  • More than 1/3 of Americans (36%) don’t meet the recommendation for physical activity (at least 150 minutes/week).
  • 40% of Americans don’t eat meals at consistent times.
  • 58% of Americans report being on screens an hour before bedtime.

Helping patients to understand good sleep hygiene is essential. To help you discuss sleep hygiene with your clients, we’ve developed this downloadable infographic on “10 Basic Tips for Good Sleep Hygiene.” Here are some of the basics:

  • Get enough sleep: Adult 18+ need 7-9 hours of sleep.
  • Get good quality sleep: Getting uninterrupted sleep is important for sleep health. During the night our body goes through distinct sleep cycles. There are four sleep stages in each sleep cycle, and each sleep cycle lasts approximately 90 minutes. Successfully completing each stage is important to the restorative process of sleep. It is ideal to get 5 -6 sleep cycles per night (Suni, E., & Dimitriu, A., 2020). For more in-depth information on sleep cycles and sleep stages, visit the National Sleep Foundation.
  • Practice good sleep hygiene: Sleep hygiene begins the moment a person wakes up, and is comprised of several health behaviors throughout the day.
  • Address stress: Increased stress has been associated with poor sleep. Practicing stress-management techniques during times of stress can help a person sleep better.
  • Address underlying conditions: Poor sleep can be attributed to underlying health conditions. If experiencing poor sleep, talk to a provider who can help (i.e., sleep specialist)

Just as we need food and air to survive, we also need good quality, and adequate amounts of sleep. As we continue to look at how best we can support people to thrive in life, sleep is one of the foundational elements for health and well-being.

Your Turn: How is your sleep? Do you discuss sleep with your client’s? How have you seen insufficient sleep impact a client’s mental health?
